The server has support for "fixed" server rooms in order to have a permanent room for hosting race maps. A little manual setup is required, and at present must be recreated on every new release and server restart.

In order to add a room for a new release, the old room must be removed first. Join the game using the old release, join the Official Racer Room, then run:

Then exit. The room will be removed.

After having removed the old room, create a new room named "Official Racer Room". Restrict join to registered players only (unregistered players don't get recorded in the stats) then run:

And leave. The `/callvote` will cause error messages as long as you are still the room admin, but they don't matter. You can quit/rejoin before that step if you wish.

Make sure you have Hedgewars working, your login/password pair (admin rights on the server required!) is stored in frontend's config.

Put `checker.ini` into `~/.hedgewars` with such content:

(Replace the version numbers (i.e. “1.0.0” and “1.0.1-dev”) and protocol numbers (i.e. 59 and 60) with the correct ones.)

If you see too many "Check failed" messages in your checker's log, check your setup. If you fixed a problem with engine, you might want to recheck previously failed replays by moving them from "`failed`" to "`replays`" folder on the game server. You may do it on a live system, that's not a problem.

It is also not a problem to stop checker at any point. If you have engine hanging for too long (shouldn't happen since 0.9.24) and `game0.log` suggests that there's nothing going on in the game being replayed, just kill the engine process to count this attempt as failed.
